title: [Improvement of standardization and accuracy of medical imaging and pathological diagnosis for better diagnosis and treatment of rectal cancer].
abstract: Rectal cancer is one of the most common malignancies in human. Because rectal cancer locates in the narrow pelvis and is close to many complicated anatomic structures, seeking R0 resection and decreasing the positive rate of circumferential resection margin become the focus of concern for surgeons. The authors review the diagnosis standard of rectal cancer in AJCC TNM cancer staging (seventh edition) and guideline of College of American Pathologists, and propose the concept of "diagnosis priority using the standardized methods". Selecting the correct medical imaging and pathology diagnosis methods is the key to improve the standardized and individualized comprehensive therapy.
